acetone is not stable, the drier it is the more likely it is to aldol condense and form diacetone and water and i think some other stuff, so if you need anhydrous acetone, prepare it as needed. Im assuming you want it for FASA, honestly, just try some fresh acetone and see how it goes, buy some that comes in a metal tin instead of plastic bottle. acetone is manufactured anhydrous so in a metal container it should stay factory fresh. they certainly dont add water to it, but 100% pure is theoretically impossible so, if they are being realistic and depending on local laws, theyll say 99% since thats all they can guarantee.
brew shops have measuring cylinders and bigass erlenmeyers. as for chemicals, its lye, vinegar, and naptha.
in my experience having glassware you can pour from without it spilling or dribbling down the side is important, a seperatory funnel is also looking to be increasingly not useful, as it turns out dmt will migrate nicely into the NPS layer just with some gentle heating in a hot water bath and occasional stirring.
unless you go a bit more exotic, you should be able to get most things locally, no need to go online for anything but information
